The main board AS1200
2.1.
Overview
The board AS1200, which is used in all D1 logic units, operates with a single-phase power supply,
regardless of whether the motor is single-phased or three-phased. It makes it possible to:
-
manage obstacle commands (opening, closing, stop).
-
manage sensor boards such as presence detectors and photocells.
-
program automatic closing with various timers.
-
work with three modes of operation: “normal”, “maintained”, and “step-by-step”.
-
supply two reversible contacts through two relays.
-
define the direction of the passage by means of sensors.
